Disaster Readiness and Risk Reduction Introduction

The topic is an introduction to Disaster Readiness and Risk Reduction.
A crane is a machine used to lift and move heavy materials.

Hazard vs. Disaster

A hazard is a dangerous phenomenon, substance, human activity, or condition that can cause harm to people, property, or the environment. This could include frayed electrical cords, loud noises, a rusty metal, or poor posture at work.
A disaster is a serious disruption to a community or society, involving large-scale losses and impacts that exceed the community's ability to recover on its own. This could include a typhoon destroying property, a sinking ship with many people on board, or widespread food poisoning. Examples of hazards could include a wet floor, an unleashed territorial dog, a closed room.

Classification of Hazards

Hazards can be classified as:
- Physical Hazards: hazards that stem from environmental factors, like vibrations, loud noises, electrical hazards.
- Chemical Hazards: hazards that stem from solids, liquids, or gases, such as cleaning products, welding fumes, pesticides.
- Ergonomic Hazards: hazards from repetitive motions, improper work techniques, or poorly designed workspaces and tools; poor posture, poor lighting.
- Psychosocial Hazards: hazards related to the work environment and organization, like stress, bullying, sexual harassment.
- Geological Hazards: hazards from the Earth's crust, such as earthquakes, volcanic eruptions, landslides, tsunamis.
- Biological Hazards: hazards from living or once-living organisms, such as blood or body fluids, fungi, bacteria, expired foods, COVID-19.
- Hydrological Hazards: hazards from the movement and distribution of water, such as floods, tsunamis, avalanches.
- Climatological Hazards: hazards from extreme weather, like drought, wildfires, cyclones, storms, etc.
- Meteorological Hazards: hazards caused by changes to the Earth's atmosphere. This includes cyclones, storms, wave surges, and typhoon.

Disaster

A disaster is a serious disruption of a community or society.
Disaster is associated with large-scale destructive events, like typhoons, earthquakes, and volcanic eruptions.
A typhoon is a hydrological hazard; but when it destroys property and affects people, it becomes a natural disaster.
An earthquake under the sea can be classified as geological hazard; but when it causes a tsunami and affects the community, it is a disaster.
Expired foods are biological hazards; widespread vomiting, stomach aches, and deaths from food poisoning is a disaster.

Identifying Hazards and Disasters

Specific examples of hazards and disasters are provided as questions.
The examples include wet floors, closed rooms, large numbers of people trapped in a sinking ship.
The examples also include unleashed territorial dogs, cities falling into sinkholes, twin-engine light planes crashing into shopping malls, traffic along Red-V road, horror movies for children, cold weather, and famine.

Probability of Risks

Examples of scenarios with their probable risks: electricity remaining on during a flood, bleach on the floor near a child, phishing, not drinking water for a day, experiencing bullying, ash cloud from a volcano, impending eruption of Mayon Volcano, cuts from rusty metal, too much vitamin C, houses without foundations.
